IMPROVEMENT m CAPIGUNS.

To all whom it may concern: V

Be it known that we, JACOB CHRIST BANDLE and ENGELBERT P. GHRISTNER, both of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in (lap-Guns, of which the following is a specification: I

Our invention relates to the class of targetguns in which the bullet is projected by the explosion of a cap only; and our invention consists in a novel combination of the trigger mechanismso disposed in relation to the nipple thatthe real barrel of the arm may be very short yet the gun be of the usual length from stock to endof barrel, the explosive cap being located a considerable distance from the trigger.

Figure l is a section of our improved gun in the position when fired. Fig. 2 is a section of the same when the hammer is set or cooked.

A is the stock of the gun, and B an ordinary barrel. 0 is a short interior barrel fitted to the barrel A in the manner shown, and secured by pin a. The barrel 0 is rifled, preferably with a seven-eighth twist, the barrel being in cross-section, composed of a series of eoncaves, I), which unite in sharp projections, on which the ball rides. The barrel U having no broad surfaces in con tact with the ball, but little friction attends the progress of the ball in its passage out, and it can therefore be expelled with great rapidity by the use of but little explosive force. The inner end of the barrel 0 is fitted with a nipple, 0, for the recepti on of the cap D, the latter beinginserted through an aperture, 1*], in the side of barrel A. The ham- 1 nier F is of plunger form, of considerable length,

to form aconnection between cap I) and the lock of the piece. The plunger slides easily within the barrel A, and connects the arm G of the look by means of the link H. The triggerguard l, which is hinged to the stock in the manner shown, and fitted with anti-triction roller 17, is adapted to move the arm G and plunger F in one'direction to cook the piece, and the spring J, which is also fitted with an anti-friction roller, (1, is employed to move the arm G and the plunger F in the opposite direction, and thereby fire the piece. The arm G is notched at theiproper point to enable the spring-catch K k to retain it in the cooked position. The trigger L M serves to release the catch, and thereby cause the discharge of the piece. Spring N retiuns the guard to the position in which it is shown after it has been swung out to cock the piece. barrel (J is clearly Fig. 2.

We claim The combination of plunger F, arm G, link H, spring J, catch K k, hinged trigger-guard I, and trigger L M, the whole being connected and op erating as and for the purpose described.

In testimony of which invention We hereunto set our hands.
